摘要： Fiber optic filaments are embedded at a bearing surface. In the context of a mechanical bearing system, the filaments wear as the surface wears. Based on the observed amount of light which is transmitted through the filaments, the degradation of the filaments is related in a measurable way to the wear of the bearing surface. The sole power requisite for inventive operation is light, for observation purposes. As compared with convention approaches to wear measurement, the invention more accurately measures wear of the bearing itself and is therefore a better predictor of servicing requirements. Inventive practice of remote wear monitoring is a viable and preferable option.

摘要： According to a preferred embodiment, a mechanical face seal assembly comprises four generally ring-shaped members and plural spring devices. The first ring-shaped member is directly fastened (e.g., bolted) to the flanged structural section located at the end of the shaft sleeve. The first and second ring-shaped members are coaxially aligned and rotatively communicative at respective radial surfaces. The first ring-shaped member is made of a metal (or ceramic) matrix composite material. The second ring-shaped member is made of a polymer matrix composite material. The second and third ring-shaped members are mated via radial openings (in the second ring-shaped member) and corresponding radial projections (in the third ring-shaped member). The third ring-shaped member has axial projections and is thereby directly fastened (e.g., bolted) to the fourth ring-shaped member, which clampingly secures the third ring-shaped member with respect to the shaft. The third ring-shaped member contains the spring devices so that they push against the second ring-shaped member, which is consequently biased against the first ring-shaped member. Since each ring-shaped member is a “split” structure having two joinable semicircular halves, the entire sealing system can be installed without disassembling the shafting mechanism. The matrix composite compositions confer structural qualities on the first and second ring-shaped members, and further afford tribological “self-healing” properties of the wear junction therebetween. The resultant benefits include fewer parts, greater compactness, longer service life, and less frequent maintenance and repair.

摘要翻译： 根据优选实施例，机械面密封组件包括四个大致环形构件和多个弹簧装置。 第一环形构件直接紧固（例如，螺栓连接）到位于轴套的端部处的带凸缘的结构部分。 第一和第二环形构件在相应的径向表面处同轴对准并且可旋转地连通。 第一个环形构件由金属（或陶瓷）基质复合材料制成。 第二环形构件由聚合物基质复合材料制成。 第二和第三环形构件通过径向开口（在第二环形构件）和对应的径向突起（在第三环形构件中）配合。 第三环形构件具有轴向突出部，并且由此直接固定（例如螺栓连接）到第四环形构件，该第四环形构件相对于轴夹紧地固定第三环形构件。 第三环形构件包括弹簧装置，使得它们推靠在第二环形构件上，该第二环形构件因此偏压抵靠第一环形构件。 由于每个环形构件是具有两个可连接的半圆形半部的“分开”结构，因此可以在不拆卸轴系机构的情况下安装整个密封系统。 基质复合组合物赋予第一和第二环形构件上的结构质量，并且进一步提供它们之间的磨损接合部的摩擦学“自愈”性质。 所产生的益处包括更少的部件，更紧凑的，更长的使用寿命，更少的维护和修理。
